I have been looking a while for hints to an elegant resolution for this problem. There is much dialogue about the use of Text::Balanced but not enough examples in the documentation for my little brain, to help me solve the riddle.

I have an example here that just pulls the expressions, I know what to do from there. I would like some ideas or code examples on a more elegant solution using one of the CPAN modules if that is possible.

There's a problem here. Traditionally, regular expressions can't match things that count (anbn). Perl RE have things that help with this (things that aren't really DFA-y); but you still probably want to look at things like Text::Balanced.

A rather obscure module I wrote some time ago experiments with using complex data structures to define how a string is to be parsed in a balanced way.

A list of tokens describes the parsing behavior. Each token could either be a string, a regexp, or an arrayref of tokens. The arrayref is used to define a "balance branch" where its first token is searched for in order to enter the branch, and its last token is searched for to leave the branch. Any string/regexp token in between is skipped over as an "escaped" literal.
